Abstract

Although the C-O stretching frequency for the system Ni>{111}c(4>x2)-CO falls in the so-called bridge region, a structure determination with photoelectron diffraction shows that the CO molecules are actually adsorbed in threefold hollow sites. These, and other recent data, seriously call into question the practice of adsorption site assignment solely on the basis of the stretching frequency of an internal mode. © 1993.
